Title: Improvements relating to hydraulic brakes
IPC: B60T13/16
Filed: 1965-10-15
Abstract: 1,113,179. Master cylinder. BARMER MASCHINENFABRIK A.G. 15 Oct., 1965 [17 Oct., 1964], No. 43845/65. Heading F2F. The Specification describes a tandem master cylinder providing separate hydraulic connections to two brake circuits, the master cylinder being provided with servo assistance from a source of liquid under pressure. The liquid supplied from a pump enters at port 3 and passes through passages 24, 23 and 18 to the outlet 5 until actuation of pedal 16 closes valve 20, 21. The pressure on piston 13 then moves this rightwards, compressing spring 36 and moving piston 14 in the same direction. As the pistons cover reservoir ports 34, 35 the pressures in chambers 32, 33 actuate the front and rear brakes respectively. If conduit 7 is damaged the piston 14 moves to close the port 30 with its pin 31, the supply to conduit 6 being maintained. If conduit 6 is damaged, pins 27, 28 abut to maintain the pressure in chamber 33 and the supply to conduit 7. If the power supply to conduit 3 fails, manual operation of front and rear brakes can be maintained.

Abstract: 912,210. Transformers. DAYSTROM Inc. Dec. 29, 1959 [Dec. 30, 1958], No. 44561/59. Class 38 (2). [Also in Group XXXVI] For calibrating an alternating current meter, a mains energized regulated power pack 37 (Fig. 2), supplies a stabilized standard current through contact 54 of switch 32, current adjusting variable resistor 39, and precision ammeter 41, movable contact 48, and a selected contact of a range of linearly-spaced tappings 1 to 15 to autotransformer 49, which in turn is connected through contact 57 of a switch 31, movable contact 51, and a similarly selected contact of the range of tappings to leads 68, 73 which are respectively connected to contact 67 moving over linearly-spaced contacts 0 to 10 of winding 63 of transformer 61, and to contact 71 moving over linearly-spaced tap contacts 0 to 0.10 of interpolating autotransformer 62 energized from winding 65 of transformer 61, which has a further winding 64 with linearly-spaced tap contacts 0 to 0.9 traversed by moving contact 69. The free end of winding 63 is connected in series with winding 64 and winding 65 over contacts 69, 71 and the instrument 46 to be calibrated is connected between the free end and the centre tap of winding 63 over leads 81, 82. Contacts 48, 51 are set to tappings of numerical order determining the number of calibration points required, resistance 39 is adjusted to produce a standard reading of precision ammeter 41, and contacts 67, 69, 71 are respectively set to contacts representing units, tenths and hundredths of amperes of the full scale reading of instrument 46. By moving contact 48 stepby-step downwards along the range of tappings, equally spaced current values for the predetermined number of calibration points may be obtained. If a half step of calibration current is required at the top of the instrument scale, switches 31, 32 may be operated to contacts 56, 58 with contact 48 at maximum to introduce a further winding of autotransformer 49 injecting an increment of current into the instrument 46 corresponding to a half step so that with the apparatus adjusted to maximum calibration current in this condition, the half step may be withdrawn by restoring switches 31, 32 after which calibration proceeds as above. A calibration current may be obtained from terminal 22 centre-tapped between 21 and 23 which is double the value of the preset current obtained from terminal 23. A potentiometer 42 shunting precision ammeter 41 is adjustable to compensate for transformer current losses. The apparatus may be mounted in a cabinet whose front panel carries the controls with calibrated dials indicating the values of the respective variables (Fig. 1, not shown).

Title: An Atomiser for Liquids
Inventor: WAGNER ERNST
IPC: B41F7/30
Filed: 1966-10-06
Abstract: 1,164,663. Damping-apparatus. E. WAGNER. 6 Oct., 1966 [20 April, 1966], No. 44645/66. Heading B6C. [Also in Division B2] An atomizer suitable for spraying a liquid to damp a printing plate in an offset printing machine comprises a plurality of curved screens 23 mounted between a pair of rotating flange members 22 whereby they are sequentially immersed in the liquid 29 in a fountain 1, and a fixed compressed air distributer pipe 13 adapted to supply a stream of air which atomizes the liquid on the screen adjacent a rectangular discharge outlet 7. The screens are so mounted on the flanges by clamps 26 and screws 27 that the openings 24 between the screens are unobstructed. The air may be discharged from the pipe 13 through a plurality of nozzles 14 having convergent/divergent sections, Fig. 3 (not shown), or through an adjustable slot (14d), Fig. 4 (not shown), which is also provided with a convergent/divergent section. The pipe 13 may be curved so that the nozzles 14 at the end thereof are further from the adjacent screen and therefore atomize more liquid. This allows the ends of the printing plates to be more intensely damped. A member 30 removes surplus liquid from the screens and a cover 4 on the fountain is slidable so as to adjust or close the outlet 7. Slides 34 adjacent the outlet 7 may be raised or lowered with aid of a cam-shaft or punched cards in synchronism with the rotation of the screens. The slides, which adjust the opening 7, may be flat, arched, serrated or perforated. The screens may have a locally varying mesh size. The air may be discharged from the nozzles &c. in the sonic region.

Abstract: 1359134 Pipe couplings C A NORGREN Ltd 17 Sept 1971 [21 Sept 1970] 44876/70 Heading F2G Units used in a compressed air line, such as valves 1, pressure regulators 3, filters 2 and oil mist lubricators (4) are preferably formed with square-faced plastic bodies 7, having sealing means 19 directly thereon. This enables the units to be held in sealing relationship by simply clamping them together and to be sealed to on a pipe-line adapter 12a, in the same way. Each unit, or series of units may thus be fitted in any size of pipe line by selecting an adapter (12) having a screw-threaded connecting bore (13) appropriate to the supply and delivery ends of the pipe. This enables one to stock adapters and obviates stocking the more expensive units integrally formed with different sizes of pipeconnecting bores.

Abstract: 1,167,095. Hydroxy aromatic carboxylic acids. TENNECO CHEMICALS Inc. 3 Oct., 1967 [5 Oct., 1966], No. 45050/67. Heading C2C. Hydroxy aromatic carboxylic acids are recovered from their alkali metal salts by adding a mineral acid to an aqueous solution of the salt to release the free acid, cooling the mixture, separating the precipitated acid, and washing the separated acid with water, at least one of the steps being carried out in the presence of a minor amount of surfactant. The surfactants may be anionic, cationic or nonionic. The preferred alkali metal salts for use as starting materials are those of salicylic acid, p-hydroxy benzoic acid or #-hydroxynaphthoic acid. The preferred mineral acids are sulphuric acid and hydrochloric acid.

Title: Improvements in valves for controlling the flow of fluids
IPC: F16K17/06
Filed: 1969-09-12
Abstract: 1,216,646. Valves. H. R. GERDTS, and W. F. GERDTS, [trading as GUSTAV F. GERDTS K.G.]. 12 Sept., 1969 [12 Sept., 1968], No. 45109/69. Heading F2V. A valve which may be operated manually or, when manually set to an appropriate position, may be operated by the fluid it is controlling, comprises a closure member 5 which opens towards the inlet passage 3 and which has formed integrally therewith a hollow guiding part 9, a stem 10 which is manually operable to move either axially but non-rotatably or rotatably by non-axially and whose terminal portion is freely contained within the hollow 21 of part 9, and an adjustable spring 17 which biases the closure member towards its open position. When it is desired to operate the valve manually, a rotation-restricting detent 13 is secured to the stem 10 so that upon turning a hand wheel 11 secured to an internally threaded bush 12, the spindle is caused to move axially within the valve housing 1 and so to control the position of the closure member 5. If the valve is to operate solely in response to the fluid it is controlling, the stem is brought into a position which lies intermediate the open and closed positions of the valve member 5 such that the valve attains an open position or is moved, against the bias of spring 17, by the fluid pressure prevailing at the inlet 3. The strength of the spring bias may be altered by loosening the detent 13 and rotating the stem through a square-ended portion 14 thereof, such rotation serving, by virtue of a key-and-slot engagement 19, 20, to alter the disposition of a spring- abuting bush 19 and hence to alter the tension in the spring.
